NHTSA Complaint #11544882 — 2017 RAM 2500

I have had two hydraulic control units (HCU) fail on this vehicle since purchasing new. The first was under warranty and failed around the 30,000 mile mark. The second failed around the 50,000 mile mark outside of warranty and parts were very difficult to find. It took the dealer nearly a year to get the part and nearly $1200 in parts and labor to fix. Many other owners are experiencing this issue. When the HCU failure is detected, the vehicle cruise control will not work. It is sometimes intermittent. When the issue is not detected, cruise control works but will be disabled as soon as the issue with the HCU is detected. Very troublesome.
